摘要： A light-shielding portion (10) shields the light spot of output light output toward a shunt position α by a projecting portion (12). Hence, the output light output toward the shunt position α does not travel to an output port (111). This allows to prevent crosstalk.

摘要： One side surface of a diffraction grating is securely held by a holder, and further, the holder is securely supported on a substrate by a supporter in such a manner that the diffraction grating held by the holder is not brought into contact with the substrate. In this manner, the diffraction grating is fixed only onto one side surface to the supporter via the holder, and further, the diffraction grating is not brought into contact with the substrate. Therefore, the lower portion of the supporter is displaced by heat generated in the substrate, however, the displacement of the supporter cannot adversely influence directly on the diffraction grating since the holder is interposed between the displaced portion and the diffraction grating.

摘要： A wavelength selection switch that includes an optical component for adjusting an optical path with an image magnification of M that is provided between a second imaging position and a mirror array. Therefore, it is possible to provide a small wavelength selection optical switch with a short optical path length that is capable of reducing the focal length of each of a first lens and a second lens to 1/M while maintaining the structure of the spectral element, the fiber array, and the mirror array according to the related art. Since the optical path length is reduced, it is possible to reduce the number of reflecting mirrors used to convert an optical path and thus reduce the size of a housing. Therefore, it is possible to reduce manufacturing costs.

摘要： In a wavelength selective switch according to the present invention, an isolator is disposed between a lens array and a first lens. The isolator includes an isolator element and a transmitting means. The isolator is disposed so that the isolator element is on light paths of input lights and that the transmitting element is on a light path of an output light. The isolator element is shared among the light paths of the plurality of input lights. The isolator element intercepts lights propagating in an opposite direction to the input lights and prevents coupling of the lights to input ports. The transmitting element transmits the output light and couples it to an output port.

摘要： A light emitting module according to the present invention is characterized in that a light emitting device and a light-emission-side lens are held close to each other by a holding part extended from part of a stem in parallel with outgoing light of the light emitting device, and light emitted from the light emitting device is refracted. A single-fiber two-way optical communication module according to the present invention has the light emitting module and, in addition, collimate lenses close to an optical fiber and a light receiving device, and is characterized in that splitting of light to a light receiving module or coupling of light from the light emitting module is performed with parallel rays. Each of the collimate lenses condenses the parallel rays to an incident/outgoing end face of the optical fiber, condenses the parallel rays to a light receiving face of the light receiving device, and outputs, as parallel rays, outgoing light from the light emitting module.

摘要： An optical semiconductor module in which displacement resulting from fixation of lenses is effectively corrected includes a first lens (102), a second lens (103), and a third lens (104) arranged between a semiconductor laser (101) and a semiconductor optical modulator (105). The first lens (102) and the second lens (103) form a collimate lens optical system. The first lens (102) converts light emitted by the semiconductor laser (101) into parallel light rays. The second lens (103) focuses the parallel light rays on the semiconductor optical modulator (105) to couple the light rays to the semiconductor optical modulator (105). The third lens (104) has a longer focal distance than the first and second lenses. Thus, displacement of the lenses resulting from fixation thereof can be corrected by adjusting in position and fixing the first and second lenses (102, 103) and then adjusting in position and fixing the third lens.
